Since 1981, Polyvance has traditionally offered a wide variety of plastic welding rod materials, profiles, and colours. In response to industry and customer demands, it is now announcing the availability of three new welding rod materials: R18, R19 and R20.
R18 is polypropylene reinforced with 15% long glass fibre. This material is now used on some radiator supports and other support components. The R18 only comes in the -04 (⅜ inch wide flat ribbon) profile and can only be used with the nitrogen plastic welder. Only available in black, the R18 may be used to reinforce the backside of welds on unreinforced PP materials. The R18 is available in 30 ft. and one-pound packs.
R19 is a high-density polyethylene reinforced with 15% long glass fibre. Although Polyvance has yet to see it used on passenger vehicles, it has been seen in industrial applications. The product is only available in natural colours (non-pigmented) and in two profiles, -04 and -08 (corner rod). The corner rod is ideal for doing fillet welds in sheet fabrication.
R20 is a blend of polycarbonate and ABS, a rigid plastic that is used on some automotive exterior panels and underhood support panels. Currently, the only available colour is white and its profile is -01 (⅛ inch round rod). It is available in 30 ft and one-pound packs.
